Pre-painted (Color Coated) aluminum alloys coil is firstly painted on the surface of the aluminum plate with good color difference control and uniform paint film. It has the ability to be folded during fabrication without any detriment to the surface. For example, PVDF paint has high weather resistance, can be guaranteed 15 - 20 years color warranty.
The coil coating process is the most efficient means of coating aluminum with an organic protective coating. It is a continuous, high-volume process that produces a consistent product in comparison to batch post-coating methods. The aluminum substrate gets degreased, chemically pre-treated and coated. Typical paint system requirements are formability, scratch-resistance, appearance, weatherability, printability, etc.
